To all whom it'may mam.-

Be it known that I, CLAUDE E. RAGSDALE,

a citizen ofiTrafalgar, county of Johnson, State of Ind1ana,., 'have invented certain new ich the following is a speciand useful Implrovements in Quick-Acting" Wrenches, of W fication.

I am awareof the fact that uiek acting wrenches are in use but, most of t em possess certain mechanical defects which have precludedtheir general use. I

The object of my invention is to provide a simple and inexpensive quick acting wrench which will draw on a nut after it has :been brought up to position.

My invention consists in the. combination and arrangement of parts hereinafter shown and described.

In the drawings Figural is a perspective view of the wrench with handle and stem cut away. Fig. 2 a side elevatioii' partially in section. Fig. 3 an end section on line Fig. 4 a cross section of the nut and movable jaw. Fig. 5 a cross section on line 5-5. Similar numerals refer to similar parts. The numeral 10 represents a stem provided with a forged head 11. and a handle 12. Stem 10 is practically rectangular in cross section with, the edge surface 13 formed of a quadrant of a circle whose diameter is equal to the width of the stem. In each edge of stem 1.0 I out threads 14 to any desired pitch. Loosely mounted on stem 10 is a movable jaw 15 provided with two extensions 16 extending down along the stem 10 for a short distance. Jaw 15 is also provided with a ring-.17 integral therewith.-

The numeral ,18 represents a nut. The end of the nut-18 is recessed as shown at 19 to go over the rin' 17. The lower end'of nut 18 is also recessed to take a washer 19 held.

to extensions 16 by means of screws 20. Nut 18 is rovided on its inner periphery with threa s on opposite quarters, the space between the threads being cut away enough'to clear threads 14 on stem 10. It will thus be seen that the movable jaw carries this nut on the rings independent from the stem. In 0 eration the nut isturned until the blank aces come over the threads 14 thus allowmg the jaw to sli ,up and down without any. I

engagements wit these threads When the proper point is reached the nut is turned unpose set forth.

til the threads therein engage with threads 14 and by a further movement of this nut it will readily be seen that the movable jaw can be drawn upward the desired amount to tighten on a nut which depends upon the pitch of the thread. To limit the movement of this nut and locate its position I provide a pin 21 which strikes the movable jaw in another point when the threads are engaged. This of course limits definitely the movement of said nut. It may be desired however, in some cases to shift this nut more than the pin would allow and in cases of this kind I provide a spring detent 22 carried by movable jaw 17 which is adapted to take into small recesses 23 in the nut. When this is used pin 21 is left out. \Vith this construe: tion it will be seen that the nut can be turned completely around if so desired. i

I am aware of the fact that wrenches are in use Where the nut is carried by threads on the movable With wrenches of this kind, however, it is impossible to draw one nut, and I do not claim any such construction.

I claim as my invention.

1. In a wrench the combination of a threaded stem 10; a movable jaw mounted thereon provided with extensions 16; a nut 18 surrounding said extensions and adapted toengage or disengage threads on stem 10; a ring 17 integral with the j aw andconcentric with the nut; and a ring 19 seeured to the lower end of extensions 16 and concentric with the nut said rings adapted to carrysaid nut, all arranged substantially as and for the purpose set forth.

2. Ina wrench the combination of a threaded stem 10, a movable aw mounted thereon provided extensions 16; a 'nut 18 surrounding said extensions and adapted to enspring detent 22 carried by the jaw and adapted to take into recesses 1n nut 18; allarranged substantially as and for the pur- CLAUDE.
